I am having trouble recording a video on my 798ci si. When I go to start recording it keeps popping up an error screen. It asks if I want to record on my navionics card even with an empty SD card installed. I removed the navionics card and used another SD card but same thing happens. I can take snap shots but not record. I thought maybe it was the SD card but I put it in my 1198 and no problems. One thing I did notice is the card hangs up in the left slot so much that I have to use needle nose pliers to get it out, Right slot is fine. I was wondering if maybe corrosion has gotten in it being it was purchased in 2009. I hesitate to spray anything into it or try to open up to inspect.
